BRAIN - human brain versus the Universe?

 -  2923  -  BRAIN  -  human brain versus the Universe?  This review follows the investigation of the similarities between two of the most challenging and complex systems in nature: the cosmic network of galaxies and the network of neuronal cells in the human brain.

---------------------  2923  -  BRAIN  -  human brain versus the Universe?

-  Despite the substantial difference in scale between the two networks which is more than 27 orders of magnitude, their quantitative analysis crosses from cosmology and neurosurgery.  This study suggests that diverse physical processes can build structures characterized by similar levels of complexity and self-organization.

-

-  The human brain functions due to its wide neuronal network that is deemed to contain approximately 69,000,000,000 neurons.

-

-   The observable universe can count upon a cosmic web of at least 100,000,000,000  galaxies.   That is about the same orders of magnitude.

-

-  Within both systems, only 30% of their masses are composed of galaxies and neurons. Within both systems, galaxies and neurons arrange themselves in long filaments or nodes between the filaments.

-

-  Within both systems, 70% of the distribution of mass or energy is composed of components playing an apparently passive role: water in the brain and dark energy in the observable Universe.

-

-  Starting from the shared features of the two systems, they compared a simulation of the network of galaxies to sections of the cerebral cortex and the cerebellum. The goal was to observe how matter fluctuations scatter over such wide and diverse scales.

-

-  The “spectral density” of both systems was calculated.  This is a technique often employed in cosmology for studying the spatial distribution of galaxies.

-

-  The analysis showed that the distribution of the fluctuation within the cerebellum neuronal network on a scale from 1 micrometer to 0.1 millimeters follows the same progression of the distribution of matter in the cosmic web on a larger scale  from 5,000,000  to 500,000,000  light-years.

-

-  The researchers also calculated some parameters characterizing both the neuronal network and the cosmic web.   The calculations were of the average number of connections in each node and the tendency of clustering several connections in relevant central nodes within each network.

-

-  These two structural parameters identified unexpected agreement levels. The connectivity within the two networks evolves following similar physical principles, despite the striking and obvious difference between the physical powers regulating galaxies and neurons. 

-

-   These two complex networks show more similarities than those shared between the cosmic web and a galaxy or a neuronal network and the inside of a neuronal body.

-

-   Cosmology, and neurosurgery studies will allow for a better understanding of the  dynamics underlying the temporal evolution of both systems.  

-

-  If you calculated the distance between the smallest dimensions in nanometers and the largest dimensions in billions of meters  the dimensions of a six foot man or woman lies right in the middle of this enormous scale.  How did that happen?   Other reviews available:

-   2786  -  BRAIN  -  how does it work?   How the brain works remains a puzzle with only a few pieces in place. Remember the brain is trying to figure out itself.  Of these, one big piece is actually a conjecture: that there’s a relationship between the physical structure of the brain and how it functions.  I’ve been thinking about that and here is what I have come up with.

-

-  2755  - BRAIN  -  be thankful for your brain?  It took 1.5 million years of evolution.  How did it get to be as good as it gets.  You may be surprised at the answer.

-

-   2423  -  BRAIN  -  how the Brain Works?  Research on Huntington’s, Parkinson’s , Alzheimer’s and Epilepsy has shown that throughout life the brain does try to repair itself through the production of new brain cells.  If the brain cells stopped growing in adults,  you have what you got.  So truth be told the brain is trying to understand itself.  Here is a little more to learn about what your brain is doing.

-

-  2355 - The Brain - it is what makes you you.  -  What was your memory just before you became conscious of it?  What is consciousness anyway?  Is consciousness something that resides at the molecular level, at the cellular level, at the neural circuit level, or at some higher organizational level in our brain?   It still remains unbelievable that consciousness can be created from mindless little neurons.

-

-   2199   -  The human brain, is a challenge for physics to explain down to the level of quantum mechanics.  At the same time into meta physics and deep into philosophy.  (Metaphysics = abstract theory with no basis in reality.)  We are navigating the narrow path between solid ground and the edge of a swamp.

-

-  1999 -  Success in life is a mindset.  So is raising or teaching kids.  .  The mindset is believing you can improve with practice and hard work rather than thinking that talent is something fixed.  The growth mindset is what makes a difference in a kid’s education.   Learn about the Pygmalion Effect.  Everyone is a teacher whether they realize it or not.

-

-  1998  -  Understanding Yourself - The Remarkable Brain. If the brain were simple enough to understand we would all be too simple to figure it out.  Serotonin is the brain’s “ don’t worry “, happy chemical. Noradrenalin is a biochemical providing the opposite effect of serotonin.  Moral lessons from Mom and Dad infuse morality into your brain. .  Regardless of our environment, or our situation, our human brain can always choose how to respond to it.    

-

-  1403  -  How to become an athlete?   To become a good athlete use your brain.  First you better understand how your brain works.  The trick is to practice to where your brain is doing the thinking for you and you hit the ball without even realizing what you are doing.

-

-  1405  -  How does the brain become a mind and create consciousness?   Human brains have figured out how the Sun shines, how life evolved from a single cell, why apples fall.  Our brains have built telescopes that see the galaxies as far back as the beginning of time.  We have built microscopes that see the contours of a single atom.  but, we have not figured our how the brain can possible do these things.  How are we even conscious that we are doing them

-

-  1024 -   Brainology Mindset.   Dr. Carol Dweck is a psychologist who maintains that success in life is a mindset.  It is not luck.  It is not genius.  It is believing you can improve with practice and hard work rather than thinking that talent in something fixed.  The growth mindset is what makes a difference in a kid’s education

-

-  922  -  Understanding yourself.   The Remarkable Brain.   If the brain were simple enough to understand we would all be too simple to figure it out.  The brain gets it complexity from having many parts, each having a specialized function.  It gets its complexity from the communications network that coordinates all of the parts through biochemical means.  It gets its complexity through evolving throughout a lifetime and over many lifetimes.  This review will help you understand not only yourself but your kids. 

-

-  868  -  Seeing with ½ your brain.   You may think thinking is hard, but seeing is harder.  Visualization uses more than ½ your brain.  While you are sitting down reading this review your brain is using 33% of the oxygen that you breath.  When you are sitting and reading you are burning 33% of the calories your body has consumed.  A total of 1/6 of what you eat gets used by your brain.  And, if you worry a lot the ratio goes up.
